  • Patent number: 7473877
    Abstract: The invention relates to a method for adjusting focus in an automated microscope. The method may comprise the steps of: providing an optical detector for image acquisition, wherein the optical detector comprises an array of sensor pixels; designating a region of interest in the array of sensor pixels to emulate a confocal aperture; directing a light beam to illuminate an object according to a predefined pattern, thereby forming an image of the illuminated pattern at the optical detector, wherein the image of the illuminated pattern substantially overlaps the designated region of interest; detecting a light intensity from sensor pixels located within the designated region of interest; and adjusting a relative focal position of an objective lens based on the detected light intensity.

  • Patent number: 7469056
    Abstract: A system for performing automated cell screening in drug discovery, including an automated microscope, a fast autofocus device and a digital imaging system. Processes are implemented in software through which relevant cellular material is segmented and quantified with minimal user interaction. Improvements in the following areas: known methods for image processing are implemented in such a way that automated segmentation is achieved; sets of known measurements (pixel counting, etc.) are implemented as methods which demonstrate aspects of biology in a reliable fashion; components for automated positioning, focusing, imaging and processing of a multiplicity of samples are integrated as systems within which the segmentation and measurement methods may be mounted; and components and methods are adapted into systems which yield more highly automated and more rapid cell screening.

  • Patent number: 7460236
    Abstract: A method of examining thin layer structures on a surface for differences in respect of optical thickness, which method comprises the steps of: irradiating the surface with light so that the light is internally or externally reflected at the surface; imaging the reflected light on a first two-dimensional detector; sequentially or continuously scanning the incident angle and/or wavelength of the light over an angular and/or wavelength range; measuring the intensities of light reflected from different parts of the surface and impinging on different parts of the detector, at least a number of incident angles and/or wavelengths, the intensity of light reflected from each part of the surface for each angle and/or wavelength depending on the optical thickness of the thin layer structure thereon; and determining from the detected light intensities at the different light incident angles and/or wavelengths an optical thickness image of the thin layer structures on the surface.

  • Patent number: 7452471
    Abstract: A column packing system comprises a control unit provided with software for monitoring the column interior pressure and/or flow through the column for use in calculating the breakpoint where a movable adapter comes into contact with a consolidated bed of bed media. The calculated breakpoint is used by the control unit to determine how much further the movable adapter has to move into the column in order to achieve a desired amount of bed compression.

  • Patent number: 7369696
    Abstract: A method of classifying cells into subpopulations using cell classifying data is described. The method comprises receiving and analyzing image data to identify object areas in the image data to determine, for at least one selected first cell, one or more measurements. A first parameter set is derived from the measurements for the first cell, the first parameter set comprising at least one of said one or more measurements. The first set of cells are classified into subpopulations, and identified to produce first identifying data. Cell classifying data for use in classifying a second set of cells into subpopulations is derived from the first parameter set and the first identifying data. A second set of cells is classified into subpopulations on the basis of one or more measurements taken for cells in the second set of cells, by use of the cell classifying data. The parameter sets of cells may be represented as vectors in an n-dimensional space.

  • Patent number: 7341202
    Abstract: Method and device for continuously producing a coherent layer of a liquid/melt of even thickness by means of centrifugal action along the entire periphery of a rotating disk (13, 113), liquid/melt being supplied to the disk around its entire axis of rotation from means (12, 112) and leaving the disk as individual droplets. The means (12, 112) distributing the liquid/melt onto the disk (13, 113) has according to the invention essentially the same speed and direction of rotation as the disk, and the liquid/melt undergoes under the influence of centrifugal action circumferentially a spreading and change in velocity across the disk (13, 113) in contact with the same.

  • Patent number: 7335898
    Abstract: A new and improved confocal fluorescence microscope is presented. The new microscope has significant advantages relative to existing implementations of microscope confocal imagers. In common with previous confocal imagers the instant invention has the advantages relative to conventional wide-field and confocal fluorescence imagers, however it addresses the drawbacks of confocal technology in terms of cost and complexity, and provides significant savings in both due to the simplicity of the components and the elimination of the need of, in particular, spatial filters such as pinholes or slits.
